I would venture to say that most of us agree that golf has a positive effect on pretty much all people who play it, so why wouldn't we want more people to be able to be positively affected by it?
Part of what makes golf so special to me is that in order to get much out of it, you have to invest a bit - I'm talking mostly about time and willingness to learn and struggle mightily, especially at first, though there is an up-front and continuing monetary cost that is unavoidable. I can find a soccer ball, kick it around with a few people for a few minutes, decide it's not for me and be in and out of the sport in the blink of an eye. But if I've never played golf before and want to give it a try, it requires both a time and financial commitment. Those who ante up and like what they experience early on tend to become golfers for life.
I think the real question is whether the $$$ amount of that ante should be lower than it is now. I say yes, but based on that "Is Financial Discrimination Moral" thread from some weeks ago, it's very clear a number of people here think it should be higher than it currently is, if anything, for various reasons that I hope will not (but fear may) be rehashed here.
Re: his seeing golf as "aspirational" (in the monetary sense, of course; he is one the Altar of the Almighty Dollar's most fervent worshippers), I'd like to ask Mr. Trump to name an income figure at which he sees someone as being able to "afford" to play golf. If it's, say, $30,000 a year annual income, I'd love to hear him explain why someone who makes $29,999 a year should not play golf but someone who makes a dollar more does. His statement holds zero authority if there's no line which, once crossed, someone is now able to afford to play golf. Necessarily he must furnish that line to have anything other than an intellectual belch in response to that question.
So I'd challenge him to draw that line and then defend it, and wish him only the best of luck in that fool's errand. Otherwise, it's clear that he regards golf as a string of pearls to be clutched, rather than a game that has a positive impact on those who pursue it.
